Could anyone help me out to identify the correct 5G NAS cause in Registration Reject in case AUSF or UDM is not responding for SBI message (Authentication Request or UECM Registration) during Initial Registration procedure?
is "Cause #22 – Congestion " appropriate? There is no such 5GMM cause "Network Failure". 5GSM has only this cause which we can not use in 5GMM message Registration Reject.
Thanks in advance.
